SQL Server 2012 :: Positions After Decimal Point

Why are there more decimal positions here

PRINT cast(111 as decimal(38,35)) / 23
--> 4.82608695652173913043478260869565217

then here

DECLARE @Zähler decimal(38,35)
, @Nenner decimal(38,35)
SET @Zähler = 111.0
SET @Nenner = 23.0
PRINT cast(@Zähler as decimal(38,35)) / @Nenner
--> 4.826086

Of course, in the upper part 23 is implicitly an integer, in the lower example it is declared as decimal. But what if I need to devide by 23.5? Why is dividing by an decimal reducing the results decimal positions?
